Answer:
2*5*7
Step-by-step explanation:
2*5=10
10*7=70
Take 2,720/34,000=.0806. This means that 2,720 is 8.06% of the original number. In order to find the percentage of decrease, you take 100%-8.06%, which equals 91.94%. Your answer is 91.94%.
$1,051. You first multiply 850 by 0.06, or 6 percent, to get $51. then add to his monthly salary. Hope this helps
Create a system of 2 equations
Let x be daily fee and y the mileage charge, then
4x + 370y = 244.50...........(1)
3x + 190y = 161.50..............(2)
If we multiply (1) by 3 and (2) by -4 and add the 2 equations we eliminate x:-
12x + 1110y = 733.50
-12x - 760y = -646 Adding :-
350y = 87.5 so y = 0.25
Plugging y = 0.25 into eqation (1) we get 4x = 244.50 - 0.25 * 370
giving x = 38
Answer is daily fee = $38 and mileage charge = $0.25 per mile.

</u>
<u>(b) Write the simplified terms of the expansion.</u>
Answer:
(a). 
(b).
Step-by-step explanation:
(a).
The binomial theorem says
For our binomial this gives
(b).
We simplify the terms of the expansion and get:
